The response.redirect method is great for moving a user from one page to another. However, it does have one major limitation--you can only use it if absolutely nothing has been written to the page. Sometimes, you actually do want to write something to the page and then redirect it, for example when displaying the status of an operation. In this case, the following JavaRedirect function comes in handy. It requires a Java compatible browser. (Note:this script has been changed to incorporate Lewis Moten's helpful suggestions).

It's a simple Delphi 2/3.0 component that will tell if you are online or not. It was extracted from one major project I'm developing, and as I have seen some requests of people needing help on how to detect if they are online, I decided to publish it. You will need the Bealsoft TDialup component previously installed to get OnLine Detect component working properly. Enjoy. Vander Nunes www.ultimate3d.com.br

ADO has a great batch update feature that not many people take advantage of. You can use it to update many records at once without making multiple round trips to the database. Here is how to use it.

Transactions are atomic operations that allow you to do multiple operations on a database as one operation. For example, if you were creating a banking application in which you deducted $100 from one account and added it to another account, you wouldn't want the operation to fail right in the middle, because the money would be 'lost'! The solution is to wrap the SQL in a transaction. If the operation is aborted in the middle (the pc gets shut off for example) the database will rollback the changes so that the initial account was never debited the $100. This will make you feel good, especially if its your bank account!

You can use ADO GetRows to output and ADO recordset to an array. This is often useful in n-tier applications when you are moving data between tiers--or if you want to persist your data in another way. http://adozone.cnw.com/default.htm
